Kibana Error dont show dashboard

A new installation of elastics with Kibana 4.1.11 suddenly does not load the dashboard. It has not changed anything.
The debugger gives me a non-specific error.
Thank you !!!

Which version of elasticsearch? Kibana 4.1 doesn't support elasticsearch 2.x or 5.x.

i use elasticsearch 4.10.4 and the system was ok during 1 week.

thanks for you answer

Please? XD
